指挥控制系统的信息安全问题
刘建永,杜婕
(解放军理工大学工程兵工程学院,南京 210007)
摘要:指挥控制系统的信息安全包括保密通信、信息认证、入侵检测和病毒防范。系统易受攻击的环节是局域网与通信链路,需采取链路加密和端到端加密措施。报文信息的鉴别认证可采用差错控制码、报文鉴别码与数字签名进行。采用反常检测统计和基于规则的检测技术进行入侵检测。病毒防范可采用反病毒软件、防火墙、类属解密和数字免疫系统等新型反病毒措施。
关键词:保密通信;报文鉴别;入侵检测;病毒防范
Problem of Information Security in C3I System
LIU Jian-yong, DU Jie
(College of Engineering Corps, PLA University of Science & Technology, Nanjing 210007, China)
Abstract: Information security of the C3I system munication security, information authentication, intrusion detection and virus defence. Parts easy to attack in the system are LAN munication link, which need to take link encrypting and point-to-point encrypting. Message information may be authenticated with error-control code, message authenticated code and digital signature. Statistical abnormality examining and examining based on rule are generally accepted in intrusion detection module. Virus defence includes antivirus software, fireproof, generic decryption and digital immunity system.
Key Words: Communication security; Message authentication; Intrusion detection; Virus defence

导弹阵地目标威胁等级的量化
侯锋
(国防科技大学管理科学与工程系,湖南长沙 410073)
摘要:导弹阵地目标威胁等级的量化,通过定义目标类型空间、参量空间及其矩阵,建立未确知测度模型。定义参量未确知测度矩阵,确定各测度函数。建立目标威胁等级测度函数规则,定义评价矩阵得出多参量未确知测度。再建立判断矩阵,确定状态参量权重系数。按最大值进行归一化处理,获得目标威胁等级。
关键词:威胁等级;量化;未确知测度;权重系数
Quantizing Method for Grade of Target Threat for Missile Position
HOU Feng
(Dept. of Management Science & Engineering, National University of Defense Technology, Changsha 410073, China)
Abstract: Quantizing method for grade of target threat for missile position, target type space, quantizing parameters space and it’s matrix were defined, and the unascertained measurement model was constructed. The measurement function was established by defining single parameter unascertained measurement
